Abstract (en)
[origin: EP0219828A2] A printer head driving mechanism having a first shaft (40) for carrying the printer head (1), a linear motor actuator (20) for driving the printer head back and forth, a second shaft (30) parallel to the first shaft (40), a counterbalance (2, 3) moveable along or with the second shaft, and a counter transmission mechanism (U) having a rotatable member arrangement (5; 12a, 12b; 50) around which two flexible members, belts or wires for example (6a, 7a; 11a, 11b; 51, 52) oppositely, each flexible member being connected at one end to the printer head (1) at the other end to the counterbalance (2, 3) so that printer head and counterbalance move in opposite directions.
